Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%. View details
三人斗地主According to the complex and changeable market situation in home, Xinhai Mining ...
三人斗地主Strive for the best recovery for you with rigorous test, accurate data and detailed report
The clients should provide about 50kg representative samples, some special samples about 200~1000kg. The simple test needs 30 working days, and the detailed test about half a year.
Sign the test contract with clients before the mineral dressing test, and make sure dressing process to test
1. Chemical Lab of Mineral Dressing Research Institute analyzes the material components (ore structure, mineral and types of ore) and chemical properties (elements, the particle size screening, density, ore relative grindability) of crude ore, and gets some data for the subsequent beneficiation test.
2. After the working of Chemical Lab, Mineral Dressing Research Room takes the mineral beneficiation test which tests the optimum conditions of dressing process. Testers take the exploratory testing at first relying on rich experience, and then the detailed testing including grinding fitness, reagent dosage, open and closed circuit test, etc. After obtaining the final products，testers should analyze them to get the recovery rate, and then takes sedimentation test of concentrate and tailings as references of equipment selection.
After finishing all the tests, Mineral Dressing Lab writes a detailed “Mineral dressing test report” by summarizing the test process. In the last part of test report, the optimum technological process and technological parameters are presented.
" Mineral dressing test report" is important basis of next mine design, and brings significance of guiding actual production.
三人斗地主Notes: Recovery rate is the final result of mineral dressing test, and the core of dressing plant construction. Every 1% reduction of recovery rate cause huge losses, especially in gold, silver mine, so the purpose of mineral dressing test is to get the recovery rate as high as possible in order to reduce the loss of clients.
Each dressing test of Mineral Dressing Research Institute is in strict accordance with the following steps (the following table data is from the relevant dressing test data of a client)
This part is described as preparation of sample used in test. The following sample process flow chart and preparation table is provide for clients

The crude ore properties determination includes: ore material component determination and ore chemical properties determination.
1, Ore material component determination 三人斗地主
The ore material component determination includes structures, types and components of ore, metal and non-metallic mineral characteristics. The following part of chart presents the ore material component determination
2, Ore chemical properties determination Ore chemical properties determination includes crude ore multi-element analysis (to make sure if the ore can be comprehensively recycled and used), crude ore particle size screening analysis, ore density determination and ore relative grindability test. The following is related charts of ore tests

Mineral dressing test includes exploration test and mineral dressing conditions test
Exploration test primarily explores the mineral dressing conditions, and then gets better process condition. The detailed test follows the process condition determination including grinding fineness test, reagent test, open circuit and closed circuit test. The following is part of the chart of exploration test and detailed test for customers.
